Purpose:
Bug fix
Description:
modi4 dies during build with strange errors.
The root cause of these is a two-year-old hack in HDF5's libtool
script that only takes effect on IRIX.
Solution:
Edited the libtool hack (by editing ltmain.sh) to correct a bug in
the hack.
Also made sure that compiler-specific DEFAULT_LIBS are used
when linking.
Platforms tested:
sleipnir, copper, modi4, sol
Bug fix
Description:
pmake (on modi4, for instance) complains about undefined variables
if it is run without the -V flag, which turns those errors to warnings.
Solution:
Added test to configure.in to see if $MAKE will allow Makefiles
with undefined variables. If not, sets -V flag in AM_MAKEFLAGS.
Ensured that all custom make targets use AM_MAKEFLAGS.
Also defined all variables that caused errors in top-level Makefile.am.
This means that pmake can be used to build hdf5 *from the top level
only*. To run make from a subdirectory, still need to use -V flag
(or use make or gmake).
Platforms tested:
modi4, heping, copper, sleipnir
Bug fix
Description:
Found the permanant fix to automake/CVS dependency problem
Solution:
Added AM_MAINTAINER_MODE macro to configure.in.
Now automake will never try to regenerate Makefiles, Makefiles.in,
configure, H5config.h, etc. when they are out of date, nor will it
print any warnings.
Developers should be very very careful to use reconfigure script,
and can add --enable-maintainer-mode flag to configure on heping
to regenerate these files correctly.
Platforms tested:
heping sleipnir copper
Configuration feature
Description:
HDF5 now uses automake to generate Makefiles
Solution:
Makefile.in files are now generated from Makefile.am files.
To reconfigure (after chaning a Makefile.am or configure.in):
/bin/sh bin/reconfigure.sh
Platforms tested:
Many
Bug fix
Description:
Catch another way that vsnprintf() can fail (this time on the HP) and
deal with that.
Platforms tested:
HP/UX 11.x (kelgia)
Doesn't affect other platforms
Bug fix
Description:
Add detect vasprintf() routine and use it instead of vsnprintf() when
formatting error descriptions if it's available.
Added configure test to detect "broken" vsnprintf() implementations which
don't return the correct number of character for strings that are too long to
fit into the buffer provided (currently a problem on the SGIs and probably the
HP).
Re-wrote error formatting code in H5Epush_stack() to handle broken
vsnprintf() implementations, etc.
Platforms tested:
IRIX64 6.5 (modi4)
h5committest
Description: Removed PABLO from the source
Solution:
Platforms tested: arabica with 64-bit, copper with parallel,
heping with GNU C and C++ and PGI fortran (but
I disabled hl, there is some weird problem only
on heping: F9XMODFLAG is not
propagated to the Makefile files
Misc. update:
Description: Intel compiler on Linux has some problem to convert long double to
unsigned int correctly.
Solution: Detect the problem in configure and define a macro to skip this test
if it happens.
Platforms tested: eirene and fuss. Simple change.
Description: The fix of the loss problem of the last 2 bytes of mantissa on sleipnir has
not been successful. It happens when converting from unsigned long long to long double.
The failure has been on and off.
Solution: Hard set a macro to disable unsigned long long->long double for FreeBSD until
a good solution is found to solve this elusive problem.
Platforms tested: sleipnir and fuss. Only sleipnir is concerned.
Misc. update:
Description: For HP-UX11.00, compiler's casting from 'long double' to most of
integers. A macro was hard set in config/hpux11.00 before.
Solution: Let configure detect this case and set the macro.
Platforms tested: kelgia, fuss, modi4. These systems are mainly concerned.
Description: For FreeBSD (sleipnir), when GNU compilers do conversion from
unsigned long long to long double, the last 2 bytes of mantissa are lost.
The impact of precision loss isn't significant.
Solution: Detect this case on FreeBSD in configure, ignore it in dtypes.c
test instead of return failure.
Platforms tested: sleipnir, fuss, modi4. These systems are mainly concerned.
Description: For HP-UX 11.00, the compiler generates 'floating exception'
when converting 'long double' to most of integer types.
Solution: Define a macro for all other systems except HP-UX 11.00. Hard set
this macro to 'no' in config/hpux11.00 to skip this test for HP-UX 11.00.
Platforms tested: modi4, kelgia, fuss
Description: Start to support software conversion between long double and
all integers.
Solution: No major changes to the algorithm. Changes to configure is to
exclude SGI for long double to integers test because there're too many problems
in their compiler.
Platforms tested: h5committest, modi4, fuss, Teragrid, arabica
Misc. update: RELEASE.txt
Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".

Misc. update:
Fix SZIP filter to dynmically detect encoder.
Description:
Solution:
See:
http://hdf.ncsa.uiuc.edu/RFC/SZIP/Szip_dynamic_12_Oct.pdf
Platforms tested:
verbena, arabica, cobalt.
Note RE testing:
All automatic tests work as before.
The feature is a configuration thing, so the tests are manual.
Tested with the following configs:
pre-release version of SZIP, with dynamic library,
1. no SZIP
2. SZIP, decoder only
3. SZIP, encoder+decoder
released (static lib) SZIP
4. no SZIP
5. SZIP, decoder only
6. SZIP, encoder+decoder
after build, switch szip in LD_LIBRARY_PATH at run time
7. SZIP decoder
8. SZIP encoder
Misc. update:
Manifest updated
Code cleanup
Description:
Update FORTRAN configuration test code to be more syntacticly correct
and not generate errors with stricter standards checking in the compiler.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest
Refactor and update fortran configuration
Description:
Changed configure.in to include the production, debugging and profiling
flags for FORTRAN in the command line.
Added '-flags' files for PGI and Intel C compilers
Added '-fflags' files for PGI and Intel FORTRAN compilers
Updated 'gnu-flags' file for GNU C compiler to not modify compiler flags
when gcc is not being used.
Make detection of the correct FORTRAN compiler a bit smarter for Linux
platforms. (And carried over some of the minor changes to other affected
machines)
Platforms tested:
Linux 2.4 (tungsten) w/PGI and Intel C & FORTRAN compilers.
Changes not tested by h5committest
Adding new 'jam' utility
Description:
New utility, plus changes to makefiles
Solution:
See http://hdf.ncsa.uiuc.edu/RFC/Jam
Platforms tested:
verbena (fortran,C++), arabica, hirdls (SGI Irix64)
Misc. update:
Manifest will be done in next checkin.
Code cleanup
Description:
Fix another batch of minor differences between the development and release
branches.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
Purpose:
Bug fix
Description:
Modification time test (mtime) would die silently on some systems. This is
because the code is very system-dependant (it relies on getting the current
time and the timezone from the OS).
Solution:
mtime test now uses TEST_ERROR macro to print "FAILED" and to output where the
failure occurred. Configure script is a little smarter about whether
gettimeofday() function returns the timezone correctly.
Further bugs will need to be addressed on a system-by-system basis.
Platforms tested:
sleipnir, arabica, verbena, copper, windows (VC7)
Code cleanup
Description:
Clean up collective chunking code a bit.
Also, add '--enable-instrument' configure flag to have a mechanism for
determining that optimized operations happened correctly in the library (instead
of just the "normal" way) by allowing 'flag' properties to be set outside the
library and set when the "right" thing happens. This is mainly for debugging
and regression checks, so we make certain we don't break optimized I/O by
accident. It's enabled by default when --enable-debug is on (which is on by
default in the development branch and off by default in the release branch),
but can also be independently controlled with its own configure flag.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
IBM p690 (copper) w/parallel
Feature
Description:
Showed the fortran compiler and FFLAGS and CXX compiler and CXXFLAGS
when the corresponding language API is enabled.
Platforms tested:
No h5committest since it is just a simple shell script change.
Tested in Eirene.
Misc. update:
Purpose:
HDF5 now supports SZIP with no encoder.
Description:
SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled.
Solution:
Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC.
Platforms tested:
Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++)
Misc. update:
Update shell scripts
Description:
Switch to generating the testh5dump.sh script at configure time, so we can
determine which filters are available to test.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too small to require h5committest
Description: A new bug is found on HP. There is float exception during conversion from double to
unsigned long long when the value of double is very big.
Solution: Try to catch the problem in configure and skip this part of test.
Platforms tested: kelgia and verbena(mainly these two machines are involved)
